Number belongs to illegal collections scammer, so if you really want some fun, just call him back repeatedly, the little worm will start crying and beg you to please stop calling his number, it's hilarious.
Yesterday, around noon, I received a call from a call from someone identifying themselves as a Mr. Ron Patterson with "Legal Delivery Services", asked for me by name, and then said he was calling about another person, saying they owed money to his client and had been trying to serve papers on them and something settling a debt or having them or someone arrested. Typical debt collection scam, wouldn't say who the creditor is, had to settle immediately or an arrest would be made etc.
